   1 make check//unix/-fPIE/-pie RUNTESTFLAGS=solib-display.exp
   2
   3 gcc -fpic -c  -fPIE -pie -o x.o x.c
   4 /usr/lib/gcc/x86_64-redhat-linux/4.6.1/../../../../lib64/Scrt1.o: In function `_start':
   5 (.text+0x20): undefined reference to `main'
   6
   7 => Change the order for overrides.

   9 One has to also use -fPIC rather than -fPIE, -fPIC is stronger.
  10
  11 The correct way would be:
  12 make check//unix RUNTESTFLAGS='CC_FOR_TARGET=gcc\ -fPIC\ -pie CXX_FOR_TARGET=g++\ -fPIC\ -pie solib-display.exp'
  13
  14 But there is a problem with testsuite.unix non-unique subdir name and also
  15 a problem with make -j parallelization of the testsuite.
